A label switched path (LSP) is a path along which packets that belong to the same FEC (that is, packets encapsulated with MPLS labels) are forwarded in an MPLS domain, as shown in the following figure. LSP networking An LSP is a unidirectional channel from the ingress to the egress. ...
What is the role of Forwarding Equivalence Class (FEC) in MPLS?() A. FEC determines how IP packets are forwarded in MPLS LSP. B. FEC determines how to establish an LSP path. C. FEC determines how a group of IP...
TLV: Type/Length/Value. The TLVs contained in PDUs of different types are different. LSP LSPs are used to exchange link-state information. LSPs are classified into two types: Level-1 LSPs and Level-2 LSPs. Level-1 IS-IS transmits Level-1 LSPs. Level-2 IS-IS transmits Level-2 LSPs....
S: 1bit, the bottom of the stack, MPLS supports multi-layer labels, that is, label nesting, S If it is 1, it is the bottom label; (4) TTL: 8bit, which has the same meaning as the time to live in the IP packet; The label is encapsulated directly between the link layer and th...
With the introduction of MPLS, which effectively provides virtual circuits (called Label Switched Paths [LSP]) across IP networks, it was only a question of time when MPLS would be used to implement proper Traffic Engineering in IP-only networks. MPLS TE follows the same principles as ATM ...
FEC determines how a group of IP packets are mapped to an LSP.
在IS-IS协议中一个LSP的LSPid为00c0.40.1234.01-02,从这里可以得到如下信息()。 A. 通过配置LSDB中AS-External-LSA的最大数量来控制LSDB规模 B. 进入超载状态之后将不再生成AS-External-LSA C. 进入超载状态之后会立即清空LSDB D. 进入超载状态之后会泛洪超载信息,使整个网络老化AS-External-L...
A session is a remote execution of a program. Programs can be shells, applications, system commands, or some built-in subsystem. Multiple session channels can be active at the same time. The interactive login session can be the invoker_shell() method, and the remote execution command can be...
